To all 'whom it may concern Be it known that we, GEORGE ALGAR, ofGrcenport, in the county of Columbia and State of New York, and MAJORALGAR, of Hartsville, in the county of Berkshire and State ofMassachusetts, have invented a new and useful Improved Instrument forCrimping Leather; and we do hereby declare that the following is a full,and eX-` act description thereof, reference being had to the drawingsaccompanying and making part of this specification. A

Our improvement consists in an instrument such as will be hereafterdescribed to be attached to the leather while on the crimp to give it aperfect finish without breaking or injuring it as is the case with thosemachines which perform the operations instanter.

Figure 1 is a perspective view.. Fig. 2 a section showing the interior,a, a. Figs. 1 and 2 represent a circular metallic plate of the requiredsize of the instrument the two extremities of which form in part thefront` end of it with such a space between them as is necessary foradmitting the thickness of the back of the boot form, and constituteinner jaws the outer of which will be now described.

Z; Figs. 1 and 2 represents them passing through an aperture o Figs. 1and 2 in the circular plate, and turning on a .suitable fulcrum el Fig.2, their inner ends and sides extending to and resting againstV a screwwhich will be hereafter described. Grooves represented by the dottedlines, e, Fig. 2 are made in these sides in which the screw 1,016, datedNovember 25, 1838.

revolves, or turns. These cross jaws so formed are acted upon and closedby `a wedge f Figs. 1 and 2 with a female screw cut longitudinallythrough its center. The screw g Figs. 1 and 2 then passes 'through anaperture in the center of the circular plate and works into the femalescrew in` the wedge so that by screwing out, (the outer end of thescrew, which is surrounded by a circular plate h, Figs. 1 and 2 restingfirmly against the back of the boot form) the wedge is made to act uponthe cross jaws gradually closing them, and while in the act of crimpingthe degree of the power of compression in the jaws, is made tocorrespond with the resistance against them.

, Fig. 2, represents springs attached to the inside of the circularplate `which pass against the outside of the inner part of the outerjaws for the purpose of opening them scribed.
